TECHNICAL FIELD

The present invention relates to a saddle type vehicle.

BACKGROUND OF THE INVENTION

A motorcycle is conventionally known wherein a position lamp provided in order to enhance the visibility of the vehicle from a person around the vehicle is disposed in front of a headlamp (refer to, for example, Japanese Patent Laid-Open No. 2009-132220).

SUMMARY OF THE INVENTION

In the motorcycle disclosed in Japanese Patent Laid-Open No. 2009-132220, although the position lamp is disposed in front of the headlamp, it is considered that a person around the motorcycle will momentarily move their eyes upwardly or downwardly to see the position lamp. Therefore, it is anticipated that time is required for the confirmation of the position lamp although it is very short. Therefore, there is room for improvement in enhancement of the visibility of the motorcycle. It is to be noted that this similarly applies also where the position lamp is a winker, and there is room for improvement in enhancement of the visibility.

A saddle type vehicle is provided wherein the visibility thereof by a position lamp or a blinker can be improved.

According to a first feature, there is provided a saddle type vehicle including: a headlight configured to illuminate the front of the vehicle; and a plurality of position lamps configured to emit light for the visibility of the vehicle. The position lamps are disposed in a left and right pair in front of the headlight. The left and right position lamps are disposed in such a manner as to sandwich the headlight therebetween as viewed in front elevation.

According to a second feature, there is provided a saddle type vehicle including: a headlight configured to illuminate the front of the vehicle; and a plurality of blinkers configured to emit light for the indication of a direction. The blinkers are disposed in a left and right pair in front of the headlight. The blinkers are disposed in such a manner as to sandwich the headlight therebetween as viewed in front elevation.

According to a third feature, there is provided a saddle type vehicle including: a headlight configured to illuminate the front of the vehicle, and a plurality of position lamps configured to emit light for the visibility of the vehicle and also have a function as blinkers emitting light for the indication of a direction. The position lamps are disposed in a left and right pair in front of the headlight. The left and right position lamps are disposed in such a manner as to sandwich the headlight therebetween as viewed in front elevation.

According to a fourth feature, the saddle type vehicle according to the first to third features is configured such that the left and right position lamps or blinkers are disposed in such a manner as to overlap at least part thereof with at least part of the headlight in an upward and downward direction as viewed in front elevation and sandwich the headlight therebetween as viewed in top plan.

According to a fifth feature, the saddle type vehicle according to the first to fourth features further includes: a vehicle body frame; a steering shaft supported for rotation at a front end of the vehicle body frame and capable of steering a front wheel; and a front cowl disposed around the steering shaft and covering a front portion of the vehicle body. The position lamps or blinkers are attached to the front cowl.

According to a sixth feature, the saddle type vehicle according to the fifth feature is configured such that a pair of left and right accommodation portions are provided in the front cowl the left and right accommodation portions are formed such that the dimension thereof in a vehicle widthwise direction decreases toward the front as viewed in top plan, and the position lamps or blinkers are provided in front of a front portion of the left and right accommodation portions.

According to a seventh feature, the saddle type vehicle according to a sixth feature is configured such that, as viewed in top plan, inner side wall portions of the accommodation portions in the front cowl which are positioned on the inner side in the vehicle widthwise direction extend to the inner side in the vehicle widthwise direction toward the front and extend along a front portion of a front fender which has a tapering shape toward the front, and the position lamps or blinkers are accommodated in a front portion of the front cowl in such a manner as to extend along the inner side wall portions of the front cowl.

According to an eighth feature, the saddle type vehicle according to the seventh feature is configured such that, as viewed in front elevation, the headlight is formed in a substantially isosceles triangle convex downwardly, and the inner side wall portions of the front cowl extend along the equal sides of the headlight of the substantially isosceles triangle as viewed in front elevation.

EFFECTS OF THE INVENTION

With the first to third features, the left and right position lamps or blinkers are disposed adjacent the headlight in the upward and downward direction in such a manner as to sandwich therebetween the headlight which is provided at a comparatively high position in the vehicle upward and downward direction. Therefore, even if a person around the vehicle does not move their eyes upwardly or downwardly, the person can easily confirm the position lamps or blinkers. Consequently, the visibility of the vehicle can be improved. Further, the position lamps or blinkers are disposed in front of the headlight. Therefore, when a person around the vehicle looks at the position lamps or blinkers, for example, obliquely from the front in the vehicle widthwise direction, the person can see the left and right position lamps or blinkers without interference from the headlight. Consequently, the visibility of the vehicle is improved.

With the fourth feature, the headlight and the position lamps or blinkers at least partly overlap with each other in the leftward and rightward, upward and downward, or forward and backward direction. Therefore, the dimension of the peripheral elements of the headlight and the position lamps or blinkers can be suppressed.

With the fifth feature, the position lamps or blinkers are attached utilizing part of the front cowl efficiently. Therefore, reduction of the number of parts can be implemented.

With the sixth feature, the outer shape of the front cowl can be made a streamlined shape from the side to the front of the accommodation portions so as to suppress the aerodynamic drag. Besides, the position lamps or blinkers are attached utilizing part of the front cowl efficiently. Therefore, reduction of the number of members can be anticipated. Further, valves of the position lamps or blinkers can be mounted on and removed from the accommodation portions. Therefore, the maintenance performance can be enhanced.

With the seventh feature, the illumination face of the position lamps or blinkers in the vehicle widthwise direction can be easily secured widely.

With the eighth feature, the position lamps or blinkers are positioned contiguously with the headlight so that they have an appearance which provides a coherent impression.

Although the embodiment of the present invention has been described, the present invention is not limited to the specific embodiment, but various modifications can be made without departing from the subject matter of the present invention. For example, while the left side portion 40L and the right side portion 40R of the front cowl 40 are configured in a spaced relationship from each other in the vehicle widthwise direction, they may otherwise be connected to each other.

Further, the side stand 90 may be provided on the right in the vehicle widthwise direction such that an erected state of the vehicle is maintained by the side stand 90 in a state in which the vehicle tilts to the right.

Further, while the under cowls 44L and 44R can be divided from each other to the left and the right, they may otherwise be integrated with each other in the leftward and rightward direction.

Further, the receiving portion 67 may project or not project upwardly from the receiving portion opening 68.

Further, while the swelling portions 44LP and 44RP are provided on the left and the right, respectively, one of them may be provided on only one of the left and right under cowls 44L and 44R.

Further, while it is described that the position lamps 48L and 48R in the embodiment described above serve also as blinkers, blinkers having only a function for direction indication may be provided at the positions of the position lamps 48L and 48R. Also in this case, similar effects to those of the embodiment described hereinabove are achieved.

Further, it is described that, in the embodiment described above, the left and right position lamps 48L and 48R are disposed such that, as viewed in front elevation, they sandwich the headlamp 47 therebetween and at least partly overlap with at least part of the headlamp 47 in the upward and downward direction. However, as viewed in front elevation, the left and right position lamps 48L and 48R may not at least partly overlap with at least part of the headlamp 47 in the upward and downward direction. However, where the left and right position lamps 48L and 48R are disposed in such a manner as to at least partly overlap with at least part of the headlamp 47 in the upward and downward direction, this is preferable in that the members are aggregated.

Further, in the embodiment described hereinabove, as viewed in front elevation, the left and right position lamps 48L and 48R are disposed in such a manner as to sandwich the headlamp 47 therebetween are disposed such that the upper end portions thereof are positioned higher than the lower end portion of the headlamp 47.
